IPROPELIJING MEANS.

Applicatoniled `Tune 13,` 192?. Serial No. 198,601.

The present invention relates to improvements in the means for propelling vessels as for instance described in abandoned application Serial No. 15,253, filed July 31, 1925, land vehicles such as automobiles or aircraft by making use of a device known as the Archimedean screw,.and it is the principal object of our invention to build such ascrew into the vessel, the automobile or aircraft equipped with a means for starting and continuing the revolution of the screw andthus propelling the vessel .through the water, all kinds of vehicles along the reads and the aircraft through the air. Y y

Another objectief our invention is the provision of a novel and improved-means for propelling` vessels by the employ of anArchimedean screw and providing such vessels with improved and novel water exhaust means. y

A further'objectof our invention `is the provision of a'propelling means for vehicles in the water, on land and in the air which is inexpensive, durable and extremely eilicient in operation.

These and other objects and advantages of our invention will become more fully apparent as the description thereof proceeds, and will then be specifically defined in the appended claims.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a side elevation of a vessel, partly in section and equipped with a means of propulsion constructed according toour invention.

2 is a top plan view thereof, partly in section.

Fig. 3 shows the use of our novel and improved propelling means in use with aircraft.

Fig. 4 illustrates the use of our novel propeiling means for driving an automobile or other vehicle.

VFig. 5 is a side elevation of a modified form of construction of a vessel'equipped with our improved propelling means.

Fig. 6 is a longitudinal section through the housing of the Archimedean screw.

Fig. 7 is a fragmentary perspective view of the screw. p

F ig. 8 is an end view o f the vessel, Figure 5.

As illustrated in Figures 1 and 2, the hull 10 of a vessel has a channel 11 built therein in the direction of its longitudinal axis, open therewith.

reception of the cylindrical mantleror housing 13 of an Archimedean screw 14. Thev screw is started to revolve about its axle 17 by means of a suitable auxiliary motor 15 and a train of intermediate gears, generally desig. nated 16, which can be uncoupled from` the screw as soon as the vessel and the screw hav acquired sufficient headway.

The, shaft or axle 17 is revolved bearings suspended from the hangers 18 and 19 respectively in the rear vandr front parts ofthe vessel depending from a deck thereof.

The exhaust of the' Awater after its use is effected by means of a plurality of oriices closed by valve plates 2O and, arrangedto both sidesl of the vessel in the hull thereof connected with the median or main channel 11 by means of transversechannels or ducts 21, said plates are normally held closed by means ofsuitable springs 22 or the like closing the orifices and channels A21 communicating VThe vessel is provided withA the customary in. suitable cabins 23, and the motor andother operating mechanism is installed in a suitable engine room 24 under the cabinV near the forecastle of the vessel.

As illustrated in Figure 3, the housing 25 for the Archimedean screw 2G is supported by a framework 27 resting on the body of an aircraft 28,and the shaft 29 is projecting beyond the ends of thehousing and is journalled in suitable bearings on brackets 30, while the rear end of the shaft 29 carries a suitable train of gears or gearing ladapted to be propelled by means of an auxiliary motor ofV any desired type for starting and Vcontinuing the revolution of shaft and screw.

`It will be clear that the Archimedean screw may also, be suspended from the fuselage out of the way of the landing wheels or gear and other operating parts for the air-ship. It may also be installed in an airship using gas bags of the dirigible, or any other type.

In Figure 4l the housing 32 of the Archimedean screw is suitably supported or arranged von the top or roof of an automobile 33 or the like. The shaft 84 of the screw oo projects beyond the ends of the housing aud is journalled in suitable bearings 36. or the like and its rear end carries a suitable train of gears or gearing 37 adapted to be driven from an auxiliary motor aboard the car. It will be clear thattheArchimedcan screw may alsoV be arranged otherwise than above described without interfering with the operating parts of the automobile. y

As illustrated in Figures 5, 6, 7 and 8, a

modified form of our invention comprises a hull 38 of a vessel with the cabins 39 and Li() the decks of said vessel carry a plurality of frame posts or standards il supporting thel cylindrical housing i2 of the Archimedean screw 43, the axle er shaft All of which tending parallel to the longitudinal axis of the vessel projects beyond the ends of the housing and is journalled in suitable bearings, andpcarries a gearing Li5 or the likev adapted to be operated by an auxiliary engine 46 of any suitable type.

It will be clear that any suitable mechanism may be employed to couple and uncouple the screw from the auxiliary starting engine, as well as any suitable well known principle involved, so may for instance the number of gills be decreased or increased according to necessity and practical require` ments or the location of the Archimedean screw may be changed in order to give the best practical results without departing from Y,

the spirit ofour invention. Y

I-Iaving thus described our invention, what we claim as new, and desire to secure by Letters Patent is:

1. A propelling means for vessels by means Y of an Archimedeanscrew comprising a`channel within the hull of the vessel extending in the direction of the longitudinal axis thereof, a housing for the screw, and a shaft therefor, means for supporting said shaft rotatably, an auxiliary engine for starting and continuing the revolutions of the screw and allowing an uncoupling and coupling of its shaft from and with said engine, and a means for allowing the waste water to be exhausted through openings in said hull.'

. 2. In aI propelling means for Vessels by an Archimedean screw, a hull having' a longitudinal channel therein' for -the reception of said screw and a plurality of side openings, plate elements hinged to the hull for closing the openings in the hull and springs for holding the same normally in closed position,

allowing anv exhaust of the waste water during the operation ofthe screw. l
